How do artists create depth on a flat surface?

In the Renaissance, painters needed to be able to translate the three- dimensional world around them onto a FLAT two-dimensional surface.

The discovery of perspective is attributed to the Renaissance architect Filippo Brunelleschi (1377-1446), who suggested a system that explained how objects shrink in size according to their position and distance from the eye.

Linear Perspective A mathematical system for creating the illusion of space and distance on a flat surface. The

One – point Perspective Two – point Perspective How are they the same….different….? Let’s review, shall we??

One – point Perspective

FIRST What is a HORIZON LINE?

One-point perspective imitates the way our eyes see object disappearing to a single point on the horizon called……

…a vanishing point! All lines converging lines, or orthogonal lines, meet at the vanishing point.

WHAT ARE CONVERGENCE, or ORTHOGONAL LINES?

Lines leading to the vanishing point are called are called orthogonal, or converging lines.

What other ways including PERSPECTIVE to artists create depth and distance on a flat surface?

: below the horizon line, objects appear higher on the picture plane as they get farther away. Above the horizon line, objects appear lower on the picture plane Pieter de Hooch Musical Party in a Courtyard Claude Monet, Hotel des Roches Noires,

Jean-Antoine Watteau, The Perspective Warm colors advance: Warm colors may appear closer. Cool colors recede: Cool colors may appear farther away. Color intensity is much greater closer to the viewer and tends to get blurry and lighter in color it goes toward the vanishing point.

: By partially covering one object with another it gives an appearance of depth Sidney Goodman, Free Fall

Georges Seurat, A Sunday Afternoon on the Island of La Grande Jatte S i z e : objects appear smaller as they get farther away.

Thomas Cole, View on the Catskill - Early Autumn : Objects have less detail as they go toward the horizon line

Two – point Perspective

Draw the corner of the object first. Draw the converging lines to the vanishing points. (these are the sides of the form)

Complete the visible sides of the box by drawing the corners, shown here with red lines. Draw yours likewise, making sure they are nice and square, at perfect right angles to the horizon line. Not even a hint of a tilt! This is the tricky part. Drawing the back, hidden sides of the box. You need to draw two sets of vanishing lines. One set goes from the right-hand corner line (top and bottom) to the LEFT VP (VP1). Another set goes from the left-hand corner line to the RIGHT VP (VP2). They cross over

simply draw a vertical line from the where the lower two vanishing lines cross, to the intersection of the upper two lines - the red line in the example. Erase guide lines. You did it! Practice

Essential Questions: What strategies do artist’s use to create depth on a 2-dimensional surface? What is perspective? How does perspective create the illusion of depth?

1.Decide on a theme…you have creative freedom with this, however, it needs to be clear. The subject can be rendered to be fantasy, sci-fi, romance, mystery…etc. Non-objective, random, etc…good layout is crucial if non- objective 2.build a box construction in 1 or 2 point with at least 5 box forms, two of which had to be touching in some way. 3.They also had to shade it in with one light source and include a foreground, middle ground and background.
